Edge CDN path with Spaces and django-storages

As per the tutorial at : https://www.digitalocean.com/community/tutorials/how-to-set-up-a-scalable-django-app-with-digitalocean-managed-databases-and-spaces

The guidance to setup CDN access via Spaces from the above is:

AWS_S3_ENDPOINT_URL = ‘spaces_endpoint_URL’ AWS_S3_CUSTOM_DOMAIN = ‘spaces_edge_endpoint_URL’

replace the spaces_edge_endpoint_URL with the Edge endpoint you just noted down, truncating the https:// prefix. For example, if the Edge endpoint URL is https://example.sfo2.cdn.digitaloceanspaces.com, AWS_S3_CUSTOM_DOMAIN should be set to example.sfo2.cdn.digitaloceanspaces.com.

With the above config, the edge path is not used - instead the path links only to the standard spaces endpoint and not the CDN endpoint.

Can you please advise if there is any further guidance on this issue? Thanks!
